Offset weight exercise device and methods of use thereof, Shalin N. Shah, application Ser. No. 11/440,062, Publication number: US 2006/0281609 A1, Filing date: May 25, 2006.

Some devices including a handle having a beveled end, an arm attached to the handle and at least one weight attached to the arm. Other devices include a central handle, a frame circumscribing at least part of the outer edge of the central handle, a rope or cable affixed to the frame, and at least one weight affixed to the rope or cable. The methods include holding an exercise device having a handle and at least one offset weight in a hand, and performing a fundamental upper extremity exercise.

There are embodiments to the Offset weight device that are somewhat similar in function to the proposed invention in that it achieves pronation, supination, ulna and radial deviation by utilizing a weight offset by an arm to the attached handle.

The Positional Offset Weight System utilizes a weight that is not offset in respect to the device but mounted in-line to the tube assembly.

For the Positional Offset Weight System the term offset is defined for the purpose of this invention as offset in relation to the center of gravity. By extending the tube assembly with the attached weight increases resistance thus minimizing mechanical advantage.

Other prior art consists of similar exercises performed with a tennis racket, where the head of the racket being heavier is used to provide resistance in performing pronation/supination exercises.

Another device that is used is a vertical shafts with attached weights. One embodiment is dumbbell that uses a spin tight fastener that uses weights on just one side. By taping the other end and using it as a handgrip some exercises can be performed, however the mass of the handle tends to counterbalance the weight and limits the effectiveness of the device. A plurality of weight to counteract this effect can lead to injury due to an abrupt change in the vector of force.

The positional Offset Weight System utilizes a light weight that has a large diameter. The larger diameter provides smoother transition for improved range of motion of supination/pronation, flexion and extension type exercises. Improvement over previous vertical shafts with attached weights, the said device uses a lightweight tube assembly to reduce the mass of the device. Due to the lighter tube assembly the device can operate with lighter weights as compared to an apparatus that use a plurality of weights. The use of rapid tube length adjustment provides the user the benefit to adjust the resistance to target specific areas using partial range and full range of motion exercises not found in other searches.

Kettlebells are yet another device that share some similarity to the proposed device. Kettlebells use a single weight that that provides a high degree of versatility by allowing the user to grip the weight at different areas of the handle. Similarly the Positional Offset Weight system offers similar versatility using the one or two hands on the grip(s) and extending or retracting the tube assembly.

DETAILED DESCRIPTION OF THE INVENTION

The preferred embodiment the invention consists of extendable telescopic tubes constructed of thin metal or equivalent material. A locking mechanism utilizing a cam lock that is mounted on the smaller tube and locks to the inner wall of the larger tube, this mechanism is locked by twisting both tubes in opposite directions. The two mating surfaces forms a contiguous tube consisting of a proximal and distal end. Bearing surfaces on the internal tube assembly or part of the cam-lock as well as the collar attaching the two tubes form another bearing section enabling a smooth operation. Two grips are press fitted, mounted inline on the outer tube to provide an option for different exercises as well as two handed operation. On the exposed end of the inner tube suitable faster is pressed or attached to the end of the tube to attach the weight. The attached weight is disc shaped and flat on two sides acting as a base to rest the device and to perform asymmetrical push-ups as well as several abdominal exercises (Note: Asymmetrical push-up has been specifically developed to use with this device)

The Positional Offset Weight System allows for a variety of exercises to be performed due to the unique design. The ability to adjust the device is derived by several features. A light weight that has a large diameter allows the user to safely perform exercises without experiencing abrupt changes that would occur with small diameter weights or weight inserts. A quick adjusting mechanism that allows for the device to be quickly adjusted to the desired length affords the user the option to quickly increase or decrease resistance. A large hand-grip or two handgrips affords the user the option to change the location of the hand on the said device to achieve the user's preference. The device can be gripped four different ways to make exercises more effective and to stabilize the device and improve form.

The Positional Offset Weight System can be utilized using different hand positions. The normal position is grasping the device similar to grasping a glass with the thumb away from the weight. The inverted position is the opposite of the normal position with the thumb towards the weight. The club position is similar to holding a golf club with the thumb towards the weight and the inverted club position has the thumb away from the weight allowing the user to perform sport related exercises.

The stabilization of the device while performing exercises can improve performance. The use of a chair, table or mat can enhance workouts. Other body parts can be used to increase effectiveness e.g. keeping the elbow pressed against the ribs when performing a reverse curl.

The said device/system system can be used alone or with other equipment to perform isolation or combination exercises. Exercises performed with the Positional Offset Weight System are resistance exercises performed with slow to moderate repetitions. The following Isolation exercises have been developed, modified and undergone human testing for use with the said device/system:

1. Shoulder Rotation

2. Upright Row

3. Lateral Raises/Bent Elbow Raises

4. Front Raises

5. Modified Shoulder Press

6. Offset Pullover

7. Reverse Curl

The following Compound exercises have been developed and undergone human testing with the said device/system:

1. Squat/Calf Raises

2. Squat/Press

3. Asymmetrical Push up

4. Asymmetrical Kneeling Push up

5. Offset Kneeling Push up Alternate Legs

6. Modified Sit-up

Asymmetrical Pushup—a push-up specific to the titled device where one hand grips the device using the weight as a base and the other hand palm on the floor creating a change in the center of gravity that requires the engagement of additional muscles to stabilize and execute a repetition.

Most fitness devices that promote weight bearing, range of motion, muscle isolation exercise require sometimes large and heavy equipment. Even light weight dumbbells can limit portability. The intended device provides a wide range of weight bearing exercises in a device that can be easily used and can be transported in a gym bag. The said device affords a quick adjustment mechanism not seen on other devices that in the same art category.
